Ten years after the end of the Great Tenma War, the world is finally at peace. Rimuru Tempest has become something beyond comprehension-a godlike being with uncountable power, unlistable skills, and a divine weapon forged from Genesis-class blades. And yet, buried beneath his calm smile and mountain of paperwork lies a quiet, aching regret. He couldn't save Shizu. He couldn't reach the Ogres in time. Despite all he's built, those moments still haunt him. But when a single question leads to an impossible answer, Rimuru realizes one thing: With his current power, even time itself is no longer a limit. Now, Rimuru travels back to the past-to rewrite his story, save the people he loves, and create the perfect future he once dreamed of. This is a story of second chances, deep regrets, and a god who still carries the heart of a slime.

The final battle with Ivarage was, to put it briefly, catastrophic. The majority of the Cardinal World and Tempest were gone. Only people with True Dragon Level strength were alive...Diablo was the only one of his subordinates who was still alive. In desperation, everyone agreed to buy some time for Rimuru to jump into the past and alter the outcome of the battle. So Rimuru, who has forgotten everyone yet remembers everyone, has jumped into the past. But the price of jumping into the past without Ivarage following him was to heavy... all of his power has disappeared. Now, a slime with two unique skills and the memory of a novel called Tensura has begun a new journey in the distant past, when Veldora was just born.
